Review for Provider for Google Calendar by DavidRGreen
Rated 2 out of 5 stars
I installed this on recommendation to gain additional functionality in sync with Google Tasks.
What I did notice after a while was the Calendar was not updating existing entries when changed outside of Thunderbird. The synchronise calendar function seemed ineffective.
Only when Thunderbird was recycled, did it make an attempt to aligning its copy of the calendar with that which was shown on Google's server.
In the end, I disabled the plugin, which removed all the calendars, so I reinstalled Thunderbird to restore the calendars that were setup during that install.
It did get the Task functionality I sought, but the cost was too high, so I continued with my previous work-around.
